Application filed May 13, 1907. Serial No. 373,311.

To all whom't't mag/'concern' Be it known that I, CHARLES ANTON BEPP- LER, a citizen of the United States, and` a resident of the city of N ew York, borough of Brooklyn, in the county-of Kings and State of New York, have invented anew and useful Improvement in Phonograph-llorns, of which the followingl is a full, clear, and exact description.

The purpose of the invention is to so con* struct a phonograph horn that the tip can be adjusted with equal facility to either a disk or a cylinder record withoutchanging the position of the body or the bell of the horn.

Another purpose of the invention is to render the horn compact in use, it having an S-shape' or is formed upon the lines of a compound curve,` whereby to bring the tip below yet not in contact with the flaring portion\of the bell, and also vto construct the horn in three separable parts, namely, a bell section, a body section, and a tip section, in order that'the horn may be stored in a minimum of space.

Another purpose of the `invention is to render the tip section not only detachable but adjustable and to provide said tip section with a sliding ferrule member capable ofv being moved to and from the record, and further, to so construct the bell section that the surface at and adjacent its outer marginal )ortion will be substantially flat or of cymbal formation, whereby to distribute the sound over a maximum of space. l

The invention consists in the novel construction and combination. of the several parts as will be hereinafter fully set 'forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iig ures.

Figure l is a side elevation ofthe improved horn having its tip sot for use in connection with the cylinder record Fig. 2 is a sectional 'side elevation of the horn showing its tip set for use 1n connection with the disk-record;

Fig.y ,3 is a horizontal section taken practi-l cally on the line 3--3 of Fig. 2 5 Fig. 4L, is a vertical section taken substantially on the line 4.-4 of Fig. 2, Fig., 5 'is'an enlarged sectional side elevation of the tip section of the horn; and Fig. 6 is a detail section through a portion of the receiving eind of t. -.e bell and en i tering end ofthe body, illustrating the application of a-latch device thereto. i

The horn consists of a bell section A, a body section B, and a tip section C. The contracted rear end of the bell section Afis provided with a plain. outwardly oliset band l0, and in the said band 1() a series of sub stantiall)r L-sliaped slots l1 is produced, the slots being 'usually three in number, the

longer sections of the said slots constituting their circumferential sections and their shorter or mouth sections are d iametrieal' sections, and extend through the outer edge of the band 10.

Each slot 11 is spanned at its mouth portion by 'an outwardly arched yor yoke shaped bridge 2,'and a spring latch 13 is secured to the outer face of the band 1() at the forward side, or what would preferablyr be the uppermost slot ll, crossing the said slot just fon ward of the bridge or yoke 12 for said slot, and'near the free end oftliis latch 13 a head le is provided, which head normally extends down into the longer or circumferential portion of the said uppermost slot at a point oppositethe mouth of the said slot, and the under face of this projection or head la is preferably more or less beveled.

The body section B is longitudinally tapering, its upper end being of the greatest diameter andy its lower end of the least diameter. At the upper end of the body sect-ion B a' band l5 is formed, capable of sliding'enlgagement with the inner face of the offsetband l() on the bell section A, and the band 'l5 on the body section B is provided with a series of pins 16 corresponding in number to the number of slots in the band member l() on the bell. -l'n' connecting' the body section B with the bell section A, the pinsare made to enter-tbc slots 1l at their mouth portions, passing beneath the bridges -l 2 at such point, and when the pins are forward oftbe'said bridges and are in the longer members of the said slots, the body section is then turned to tbe outer ends of the said longer portions :ofi tbc slots ll, whereupon=tl1e`lheadlLl of the 1 latch i3' will automatical dropbehind the uppermost e pin and prove t' from "moving in its slot, tbus lockingtliebody section to the bell section. in a reniovablefmanner,

' 'The bodysection B in' addition to being' 'longitud' ily tapering given' a downward .l curva ture; 'thecuryature being 'are pronounced, as is'showmso ies are exteriorly secured, and

' engagement with corresponding that thelower end of the said body section will be well within the plane of the outer edge of the bell section at its bottom portion, since when the body section is fixed to the bell/section a line drawnthrough the' center of one would pass through the center of the other. l' At t e lower redu'ced end portion bof the body section B usually two op osi-ng pins 17 t ese pins are adapted for use in attachingqto the body section B a tip section C. T is tip section is likewise longitudinally tapering, being of greater diameter at its upper or inner end and of least diameter at i'ts lower or outer end.' The tip section C is reversely curved to the curvature of the body section B, the curve being in direction of the rear of the horn, and the said tip section C is not only removably connected-with the body 'section B but is also adjustably connected therewith.

' To that end at the upper extremity of the tip section C, a hub 18 is formed, as is illustrated best in Fig. 5, and vthis hub is adapted to receive within it the reduced lower? end of the body section B, and the said hub 18 is provided with opposing circumferential slots 19, which as illustrated in Fig. 4 preferably correspond in length to the quarter of the circumference of the said tip section at its reducedend, and each slot 19 is provided with an entering or mouth section 20 at its,

central ortion extending out through the 'edge of t e hub 18.

When the tip sectio'n is to be laced upon the body section, the pins 17 of t e body section are received in the slots 19-of the tip section, passing beneath arched members 21, that constitute bridges for the mouth portions of the said slots, and when the pins 17 are forward of these bridge members 21, `the tip C is turned so as to bring' the pins 17 in end portions of the slots 19,' whereupon the tip C will have a downwardly extending or :substantially vertical position, shown"in Fig. 1, which position it occupies when thehorn is to be used in connection with the cylinder record.

If the hom is to be used in connection with a disk record, the tip C is turned so as to bring 'the pins 17 of the body B in engagement with the other end portions of the slots 19 in the tip, whereupon the lower end of the tip will be carried in to the horizontal position shown in Fig'. 2, bringing its outlet to face the disk. It will be observed that in either position of the tip C it is to the rear of the bottom outer portion of the bell of vthe vhorn, quite close thereto but separated a-con venent distance therefrom, so as to render the device whenits parts are connected exceedingly compact, and when the device are separated it can be packed in avery small compass.

Usually adjacent the lower end of the tip C the parts ofm an exterior band or boss 21 is formed, as is articularly show'n in Fig. 5, and a ferrule 22 1s mounted to slide upon the-exterior of the tip at a point below the band or boss 21", and this ferrule 2 2 is provided with a longitudinal slot 23 through which a pin 24 extends .from the said tip, as is also best shown in Fig. 5, which ferrule enables the tip to be lengthened or: shortened to accommodate it to the record cylinders or record disks of different styles of phonographs.

The outer face of the flaring portionof thev bell section A at its outer edge and at a part closely adjacent thereto, is provided with a flattened surface 25, so 4as to give to this ortion of the bell the shape of the striking lace of cymbals, and vsuch formation tends to distribute the sound to a much greater degree than when the said bell is of an'ordinary gradual curvature from its inner portion to its outer edge.

'I do not .limit myself to the exact coni struction herein shown and described, as the details of the invention may be modified or changedwithout departing from-the spirit thereof. The ferrule 22 is particularly designed to prevent the horn leaving the speaker of instruments of the cylinder type after the machineis set in motion,. as it adjusts itself to the speaker. Eyes27 .and 27' are secured to the upper portion flthe bell A at the outer marginal portion and to. the bod f B, and said eyes are connected by a lengtlr of chain 28 having connected therewith a. shorter stretch 29 that is connected with the usual stand,whereby the horn is capable of a free rotary swinging movement., since there' is no coupling between thc .horn and the speaker, tie. horn being simply 'supported over theA speaker independent thereof. The suspension,` chain '29 is'in a line with the lower end of the ti' C; as is shown by the broken line 30, so trat in hanging the horn the tendency of the ferrule end of the tip will be to remain over the speaker. In practice,

the bell of the horn occuples a more upright position than is illustrated.
